Hi all,

I have two xts objects...and they have coulmns with the same names.ie their
column represent the same variables.

The only difference is that the values in the rows may be different. At
precisely the same timestamps the observations can be exactly the same.

How do I find the intersection of these two time series ie the rows where
the observations are identical including the time stamps?

How do I find intersection where a few specified coulmns are identical
including the time stamps?

Thanks a lot!
